🔎 UNIDENTIFIED Two similar stones that seem to be different. Any opinions?

I'm going to add two rocks and I know what neither are. They are very rough like sand but not sandstone if that makes sense. Maybe it is just weathered sandstone, but, either way if you all know more than me and I know you do some I'd help would be appreciated. They, like all me rocks come from northern louisiana. Like I say, they feel similar in touch as in they're rough, but the first one seems to be all together different. Thanks for any help

Natural stone with water erosion, looks like sandstone to me.
